New AI Solves a Millennium Prize
OpenAI's new AI model solved the Navier-Stokes Millennium Prize problem within 88 hours of training, surpassing its predecessor Astra. This breakthrough occurred after researchers Tristan Buckmaster and Levent Alpoge published related results using LLM assistance, prompting OpenAI to accelerate its own efforts. The event highlights the rapid pace of AI progress and the significant computational resources required to achieve such mathematical milestones.
- ▪OpenAI's internal model solved the Navier-Stokes problem in 88 hours, with Astra completing the Lean formalization in an additional 17 hours.
- ▪Researchers Tristan Buckmaster and Levent Alpoge had previously published results on finite-time blowup for incompressible porous media and Euler equations using LLM assistance.
- ▪The AI agents used approximately 130 billion output tokens to resolve the Navier-Stokes problem, incurring an estimated cost of $22 million for a regular customer.
- ▪OpenAI initiated the intensive computation after hearing a false rumor that two Millennium Problems had already been resolved by another entity.

Brand New AI Solves a Millennium PrizeZvi MowshowitzSep 13, 2026111439ShareThe first Millennium Prize, Navier-Stokes, has fallen to AI.A deeply unfortunate situation has arisen involving what should have been some combination of a positive story about new progress in AI-assisted mathematical research and yet another opportunity to freak out about rapid AI progress. Or, as we call it around here, Tuesday. The Real Story Is The New Model That Is Better Than AstraKeep your eyes on the prize. There are three stories here.The first story is much more important than the second story, which in turn is much more important than the third story.
